  • Ad Hoc Networks: A Flexible and Robust Data Communication 
    Abolhasan Mehran; Wysocki Tadeusz (Auerbach Publications - Taylor & Francis Group, LLC, 2006)
    The 1990s witnessed a rapid growth in research interests in mobile ad hoc networks (MANETs). The infrastructureless and dynamic nature of these networks demand that a new set of networking strategies be implemented to ...
  • Boundary Node Selection Algorithms in WSNs 
    Rafiei Ali; Abolhasan Mehran; Franklin Daniel; Safaei Farzad (IEEE, 2011)
    Abstract - Physical damage and/or node power exhaustion may lead to coverage holes in WSNs. Coverage holes can be directly detected by certain proximate nodes known as boundary nodes (B-nodes). Due to the sensor nodes ...
  • Characterising the Behaviour of IEEE 802.11 Broadcast Transmissions in Ad Hoc Wireless LANs 
    Wang Jerry; Abolhasan Mehran; Franklin Daniel; Safaei Farzad (IEEE, 2009)
    This paper evaluates the performance of the IEEE 802.11 broadcast traffic under both saturation and non-saturation conditions. The evaluation highlights some important characteristics of IEEE 802.11 broadcast traffic as ...
  • A Comprehensive Survey on RAT Selection Algorithms for Heterogeneous Networks 
    Al Sabbagh Abdallah; Braun Robin; Abolhasan Mehran (World Academy of Science, Engineering and Technology - WASET, 2011)
    Due to the coexistence of different Radio Access Technologies (RATs), Next Generation Wireless Networks (NGWN) are predicted to be heterogeneous in nature. The coexistence of different RATs requires a need for Common Radio ...
  • Distributed MIMO systems using Asterism decoding 
    Conder Phillip; Gao Jason; Abolhasan Mehran (IEEE, 2007)
    Multiple Input Multiple Output (MIMO) systems have received enormous attention by researchers as they can provide a roughly linear increase in capacity of wireless communications systems by using multiple transmit and ...
  • Dynamic zone topology routing protocol for MANETs 
    Abolhasan Mehran; Wysocki Tadeusz (John Wiley & Sons Ltd, 2007)
    The limited scalability of the proactive and reactive routing protocols have resulted in the introduction of new generation of routing in mobile ad hoc networks, called hybrid routing. These protocols aim to extend the ...
  • Efficient and Highly Scalable Route Discovery for On-demand Routing Protocols in Ad hoc Networks 
    Abolhasan Mehran; Lipman Justin (IEEE, 2005)
    This paper presents a number of different route discovery strategies for on-demand routing protocols, which provide more control to each intermediate node make during the route discovery phase to make intelligent forwarding ...
  • An Efficient Opportunistic Cooperative Diversity Protocol for IEEE 802.11 Networks 
    Hagelstein Brett; Abolhasan Mehran; Franklin Daniel; Safaei Farzad (ACM, 2010)
    Opportunistic cooperation promises to enhance the user experience when streaming media over wireless devices by improving wireless network reliability at the link level. This paper presents DAFMAC, an efficient cooperative ...
  • An efficient opportunistic cooperative diversity protocol for IEEE 802.11 networks 
    Hagelstein Brett; Abolhasan Mehran; Franklin Daniel; Safaei Farzad (Association for Computing Machinery, Inc. (ACM), 2010)
    Opportunistic cooperation promises to enhance the user experience when streaming media over wireless devices by improving wireless network reliability at the link level. This paper presents DAFMAC, an efficient cooperative ...
  • Highly Scalable Routing Strategies: DZTR Routing Protocol 
    Abolhasan Mehran; Wysocki Tadeusz (Springer Science+Business Media, Inc., 2005)
    In this paper we present a simulation study of a hybrid routing protocol we proposed in our previous work [4] [3]. Our hybrid routing strategy is called Dynamic Zone Topology Routing protocol (DZTR). This protocol has been ...
  • Low Complexity Interference Aware Distributed Resource Allocation for Multi-Cell OFDMA Cooperative Relay Networks 
    Odeh Nidhal; Abolhasan Mehran; Safaei Farzad (IEEEXplore, 2010)
    In this paper we focus on the subcarrier allocation for the uplink OFDMA based cooperative relay networks. Multiple cells were considered, each composed of a single base station (destination), multiple amplify and forward ...
  • On Separating Route Control and Data Flows in Multi-Radio Multi-Hop Ad Hoc Network 
    Wang Jerry; Abolhasan Mehran; Franklin Daniel; Safaei Farzad; Lipman Justin (IEEE, 2007)
    Ad hoc networks typically require a significant amount of routing and control information to be distributed in a timely and reliable manner throughout the network, particularly in dynamic environments. As traffic levels ...
  • On the Symbol Error Probability of Multihop Parallel Relay Networks 
    Barua Bappi; Abolhasan Mehran; Safaei Farzad (IEEE, 2011)
    In this paper we analyze the symbol error probability (SEP) of a cooperative multihop parallel relay network in Rayleigh fading channels for M-ary Phase-shift keying (M-PSK) modulation. The general closed form expression ...
  • An optimised resource aware approach to information collection in ad hoc networks 
    Lipman Justin; Abolhasan Mehran; Boustead Paul; Chicharo Joe (Elsevier BV, 2005)
    In ad hoc networks there is a need for all-to-one protocols that allow for information collection or â¿¿sensingâ¿ of the state of an ad hoc network and the nodes that comprise it. Such protocols may be used for service ...
